Smart home tech is becoming more common. So much so that it’s worth considering when it comes time to sell your home, especially because it can be so expensive. Does it add value to your home Or is a perk? Appraisers are looking for things like number of bedrooms, location, and other essential amenities. Some whole-house automated systems (like Control4) might add some value. Basic upgrades like a Nest thermostat or a Sonos smart sound system, aren’t going to do much for you.
